Have your old flapper boxes become rusted, stuck, or has the pull lever broken off? Replace them with brand new ones and assure that your heat will be working fine for many years to come. |

| $149.50 | | | Air Block-Off Plates | The 911 engine is an air-cooled engine. As such, it receives much of its cooling via the flow of air from the large upright fan mounted on the engine. Improving the flow of the air helps to keep the engine running cooler, which translates into increased longevity. Since the 911 uses its fan to supply air for the passenger compartment heating system, some of this air is diverted away from cooling the engine. With air cooled cars, the passenger compartment heat comes from air blown through sheet metal passages that surround the exhaust headers.
If your heater in your 911 is not working or is disabled, then you might want to install what is commonly known as an air block-off plate on the side of the engine fan. Towards the left side of the engine, there is an air outlet that drives the heating system for the car. On the early cars, this flow of air was the only mechanism to push air into the passenger compartment. This arrangement didn’t provide adequate warm air flow and in later years, Porsche installed an additional blower motor in the engine compartment. If your heater system is not working or disabled (as it usually is on a track car), then a good upgrade is to replace your heater air-flow plate with a block-off plate. This block-off plate does exactly what its name implies. It blocks the flow of air, and thus diverts it back over the cylinders, where it can cool the car. |

Perhaps one of the little tips have fallen off of the end, so that you can't reconnect it to the flapper boxes? Fix your heater system once and for all with a brand new cable. Also replace your heater barrel nuts if they are missing from the flapper boxes. |
